Hi,
I just run into an annoying feature of libtool. I'm trying to compile a
xmms-plugin, which works as shared object (.so, no version). As the code
is C++, the shared object needs to be linked against libgcc so
__builtin_new is resolved properly. If I add -lgcc to the c++ command that
libtool runs, this works fine. If I add the same -lgcc line to the libtool
command linking things, libtool warns me that I'll need a libgcc, but then
discards(!) the one I give it on the command line explicitly.
Is there something that can be done against that?

Here's the typescript. Note the -lgcc in the libtool call, but not in the
c++ call:
